BUCKBOARD-WAGON.

SPECIFICATION forming part of Letters Patent No. 242,371, elated May 31,1881.

Application filed October 12, 1880. (No model.)

To all whom it may concern:

Be it known that I, JAMES H. RoBBlNs, of Dansville, Livingston county,New York, have invented a certain new and useful Improvement inBuckboard-Vagons; and Ido hereby declare that the following is a full,clear, and exact description of the same, reference being had to theaccompanying drawings, in which Figure 1 is a plan of a buckboanl-wagon,

IO showing my improvement applied thereto. Fig. 2 is an elevation of thefront spring and its connecting parts. Figs. 3, 4, 5, and 6 are detailviews.

My improvement relates to that class of vehiclesknown asbackboard-wagons5 and the invention consists in an improved arrangementof thejoints connected with the half elliptic springs, as hereinaftermore fully described.

In the drawings, A A represent the axles.

B is the reach. 0 O are angular braces c011- nectin g the reach with therear axle. D D are the half elliptic springs; and EE are the goosenecks,all of well-known form and construction.

My improvement is as follows:

G is a ball cast or formed on the upper end of each goose-neck, andpreferably chilled or otherwise hardened. H is a socket which fits 0 andturns upon this ball, and is attached to the end of the spring. Thissocket is madein halves a a, which are counterparts, fitting face toface, as shown in the front view, Fig. 4:. At the top the parts of thesocket have ears I) b,

3 5 through which passes a screw, 0, for clamping the parts together. Atthe bottom it has two lugs, d d, between which rests the eyef of thespring, and through which passes a bolt, g, forming the pivot to attachthe spring and al low it proper play. The screw 0 and bolt 1 form theclamps at top and bottom to fasten the halves of the soekettogether andhold it upon the ball.

By the use of the ball and socket a univer- 5 sal-joint action issecured, which enables the spring not only to turn laterally\vi'thoutbinding, in the same manner that the knuckle does, but also toturn quartering, or at any angle between a longitudinal and crosswisedirection.

This is a "cry great advantage, as 4 the motions of the spring, underits vibrations, are such as to bring a quartering or angular twist uponthe parts. At the same time the spring is allowed to expand and contractlongitudinally by the employment of the lugs or bearings d (I, attachedto the socket, and the pivot g, which passes through the same.

To allow the proper joint motion of the socket upon the ball, the eyeIt, through which the goose-neck passes, is madelarger than thegoose-neck itself, so that the socket may move in any and all directionsto the proper extent and without impediment.

By the means above described the greatest freedom is allowed to thespring in all directions, and it is prevented from rolling the axles.The construction of the socket in halves, with cars at top and bottom,the latter serving as the bearings for the spring, secures greatcheapness and simplicity, and enables the sockets to be attached uponthe balls without difficulty. A ball and socket is used at each end ofboth the front and rear springs.

I and K represent two irons used at the front end of the wagon, thefirst being attachcd on the under side of the head-block or bolster J,and the last being attached on top of the spring D, with a leather orother suitable packing between. These plates have two circles, m m, ofsmall diameter, which fit together and turn one on the other. The lowercircle has a concentric rib, a, on its top, which fits in acorresponding groove, 0, of the upper circle. The lower circle has alsoa c'onical thimble, p, which projects upward through 8 5 an opening inthe center of the upper circle.

In the bottom of the lower iron, K, is a square socket, s, which extendsbut part way through and has a shoulder at the top. In this socket restthe heads '21 w of two bolts, M and N, the first passing up through thethimble p, and thence up through the head-block, and serving to hold thespring to the head-block, and the latter passing through the leaves ofthe spring and serving to hold them together. 9 5 The upper iron, I, isattached to the headblock by means of bolts 3 and the lower 011e,

K, is attached to the spring by clips 2 z.

I do not claim a knuckle turning laterally on a goose-neck and providedwith a pivoted 10o link or clevisfor receiving the end of the spring;which latter also serves as the axis for the end but of the spring, asherein shown and described. What I claim is In witness whereof I havehereunto signed In a bnckboard-wagon, the socket H, conmy name in thepresence of two subscribing 5 strncted in halves a a, fitting togetheron the witnesses.
